Specify historical date for click performance report

Hi

I am trying to download historical data for the click performance report.  I can get it to run with the YESTERDAY and TODAY date range type, but I want to be able to go back and download the last 90 days worth of data.  I am using the Java adwords.axis examples as a base, and trying to do something like the following:

        DateRange dr = new DateRange();

        dr.setMin("20160401");

        dr.setMax("20160402");

        selector.setDateRange(dr);

        reportDefinition.setDateRangeType(ReportDefinitionDateRangeType.CUSTOM_DATE);

        reportDefinition.setReportType(ReportDefinitionReportType.CLICK_PERFORMANCE_REPORT);

        reportDefinition.setDownloadFormat(DownloadFormat.CSV);

However, I get the following error:

---

[07 Apr 2016 11:50:59,539-report_download:WARN:main] Response received with status code 400 and message: Bad Request

Report was not downloaded due to: HTTP Response Code: 400, Trigger: A single day DateRange is required for reportType: CLICK_PERFORMANCE_REPORT, Type: ReportDefinitionError.INVALID_DATE_RANGE_FOR_REPORT

---

If I omit the date range type altogether but leave the min and max in I get the exact same error.

Any help appreciated.

Thanks

Neil
